It's a weird thing, I mean why not just set up some post game dungeon that lasts forever after you beat the game and put the absurdly hard crap in there?
You mean like a lot of JRPGS do?
For example, Star Ocean 3 has Sphere 211 (That's 211 floors) and 2 other post-game bonus dungeons.
FFX-2 had the 99 floors of the Via Purifico.
Parasite Eve had the 77 floors of the Chrysler Building.
Dragon Quest 8 had a completely different ending, post-game, after some intensely difficult boss fights.
Disgaea... enough said right there...
This is actually standard practice in JRPGs already. Haven't really seen it much for Western games though, beyond money grabbing DLC.
